Each week, Digital Spy rounds up the biggest mobile gaming releases with reviews and trailers. This week's games include the future legend of a rhythm alien, an outright alien invasion and a more mundane invasion of a garden by a friendly rabbit.

The game is almost more of a rhythm game than an auto-runner actually, with each jump accompanied by notes that add to the soundtrack, and a melody that expands as you collect items throughout each level.

The first three worlds are available, with the last two marked as "coming soon". Each world has ten main stages and a boss, along with four bonus levels and five retro-style 2D stages that can be unlocked with gold nuggets you collect.

It's anything but a flawless port though, as tapping the screen for jumps is about half a second less responsive than it needs to be for the game's precision timing.

It seems Gaijin Games was aware of the issue, making it so that you automatically ascend any stair obstacles since the jump reaction time just can't accommodate tapping to jump as quickly as those portions would demand.

The swipe controls, which allow you to slide under obstacles, kick down barriers, or dance for extra points, are also rather haphazard in their responsiveness and often register as a jump instead of whichever action you intended.

There are fleeting moments when everything works as it should and there is a glimpse of the excellent game released on other platforms, but an unintended jump or some other fault of the controls quickly kills the mood.

The spotty controls don't exactly make the game unplayable, but it certainly makes playing an unpleasant experience. BIT.TRIP RUN is a bad version of an amazing game.

You don't have complete control over your tanks, with the game instead offering a tactical view to navigate a path through the pre-set roads in each mission.

New to Anomaly 2 is the ability for each tank to transform by double tapping on it, morphing the unit into a new vehicle with unique strengths and weaknesses.

There is a lot of strategy in figuring out the right tanks for the job, and managing the appropriate times to use each vehicle's transformations. Different routes may offer more resources to equip and upgrade your convoy, but at the cost of more dangerous alien towers.

Support abilities like repairs and decoys can help mitigate the risk, but must be used wisely since their limited supply can only be replenished by destroying alien towers.

Along with a lengthy single-player campaign, Anomaly 2 comes packed with a satisfying multiplayer mode that pits one player as the attacking convoy against a player placing alien towers.

While transforming vehicles don't completely change the game from Anomaly 2's predecessors, it does offer a few new strategic twists on the series' already strong gameplay.

Players swipe to move in the desired direction, and if the square has a ripe veggie Ben will pick it up and throw it on his back. Collecting three or more matching veggies clears the group, but if the stack gets too high it will topple over and wake up the garden's guard dog.

Each level gives you a specific target number of each coloured vegetable, as well as the order the colors need to be collected in.

The level goals mean that you'll sometimes need to throw some of the wrong color on your stack in order to reach the target you need, and the levels can get incredibly challenging when it comes to meeting all the goals within the prescribed number of matches.

Stack Rabbit can sometimes be too challenging for its own good, since the veggies are randomly placed each round and a random color will grow back to replace any that you pick up.

This means that success or failure often relies on how lucky you are instead of how clever you are at solving puzzles.

There are boosts you can buy to add extra lives, extra turns, or increase how high Ben can stack, but these are only bought with actual money rather than having any option for in-game currency.

Stack Rabbit offers inventive and fun puzzle matching with a wonderful art style, but can prove too frustrating in its later levels due to a reliance on luck.
